Sum to Fifteen:Magic Square 3x3

Magic squares of order 3x3 consist of the numbers 1,2,...,9 arranged in a square so that the sum of any row, any column,
and both main diagonals is equal to 15. There are also magic squares of order 4x4, 5x5, etc., but we'll stick with 3x3 here.
Once you discover one solution, you can exercise your brain by creating others by rotating your solution or reflecting it across a
row, column, or diagonal. After pressing the Start button, click on a square and type a number. You can use each number only once;
typing the backspace or delete key will erase a number.
